Did you like it? Was it fast? I didn't see a fin? I watched your vids on Facebook - I was curious what a fall would be like - you did that, I see you can clear the ama It also looks like you could try one ama, like an OC Canoe?

Took me a bit to visualize "dangerous" in a capsize - but then I realized, the one ama could go vertical and you would have to high-jump it or duck under it - or eek! maybe get smacked by it if you fell with the direction of the roll.

Some the pics show both ama touching, some one - can both fly out of the water? or is 13" just too tippy for that?

Facebook isn't translating to English for me but I can get a good idea what is going on. Watched your video where you collected an armload of canoe paddles - that cracked me up.

Bean was probably joking but you'd have a lot less drag with a foil ama--a little float for initial stabilization and then a surface-piercing foil for stabilization. You could do that with just one set of iakos. Probably best to do it with a single front iako so it wouldn't hit you if it hulis. When and if I get my OC1 to Hood River I want to experiment with that. Current design has a lot of drag from the interference waves between the ama and the hull--they're close enough so the bow waves can't pass behind, and the amas are very long so the wave probably even drags in rebound.

The main reason sailing cats are so wide (besides resisting tip from the sail) is interference drag. The SIC Standamaran suffers from it.

Probably so. From the start,I had in mind to be able to easily change everything. Different amas, longer iatos, etc....

I can try with a much longer iato, but I'm not sure that with a lenght/width ratio of 20 and at relatively low speed the bow wave is significant. The standamaran is 28" wide, hence only 14" between the bows. I currently have 3' between hull and ama bows. I can push it up to 5' on one side for the tests.

Standamaran has 18" between bows but who's counting, still, as Bill says, produce interference drag. That said, I'd take a Standamaran over this design every time unless it's strictly flatwater.Too many chances for injuries otherwise.

I would rather explore the attached design where you stand on the ama (and fly the other one), seem much more usable and less injury prone. Not sure how much hit you'll take on speed withthat design, but judging by how fast the Standamaran is compare to my other 16 in many conditions, this design could probably be more efficient and comfortable.

But kudos to you for pushing the envelope, I love seeing this stuff and I'm sure you're having ton of fun with it.

How can you stand on a ama if its not at least 100 liters ? My amas are 12' long and only 45 liters.

I don't see so many chances for injuries. The board is so stable you can ride it on one foot, and it's only plastic. I could add patches of deck pad on the iatos just in case.

If you look on the design above, you're not really standing on the ama, weight is distributed. 45 liters sounds doable.

Going back to your board, I'm sure it is super stable and you can ride it in flat water with your eyes closed no problem, but what happens whenthe water gets rough, like open ocean rough? I see the chances of falling and falling the wrong way increase substantially.

If it's not where you're aiming with this design and it only meant for flat water, then I could see myself on this board having fun
